Preliminary specification
9-bit analog-to-digital converter for
digital video
TDA8761
FEATURES
9-bit resolution
Sampling rate up to 30 MHz
DC sampling allowed
One clock cycle conversion only
High signal-to-noise ratio over a large analog input
frequency range (8.5 effective bits at 10 MHz full-scale
input at f
clk
= 30 MHz)
No missing codes guaranteed
In range (IR) 3-state TTL output
TTL compatible digital inputs and outputs
Low-level AC clock input signal allowed
External reference voltage regulator
Power dissipation only 360 mW (typical)
Low analog input capacitance, no buffer amplifier
required
No sample-and-hold circuit required.
APPLICATIONS
Analog-to-digital conversion for:
Video data digitizing
Digital Video Broadcasting (DVB)
Cable TV.
GENERAL DESCRIPTION
The TDA8761 is a 9-bit analog-to-digital converter (ADC)
for professional video and digital video set box
applications. It converts the analog input signal into 9-bit
binary-coded digital words at a maximum sampling rate of
30 MHz. Its linearity performance ensures the required
conversion accuracy in case of 256QAM demodulator
concept and for all symbol frequencies. All digital inputs
and outputs are TTL compatible, although a low-level sine
wave clock input signal is allowed.
